Abstract
The present invention relates to a method for manufacturing an aqueous glucose solution from the starch components of Triticeae grains, for example from rye, triticale or in particular wheat grains. The invention also relates to a glucose-based fermentation method for manufacturing organic compounds in which the glucose manufactured for fermentation is produced from the starch components of Triticeae grains by way of a method according to the invention.
Claims36
A method for producing an aqueous glucose solution having a glucose content of at least 32% by weight from the starch components of grains of Triticeae plants, which comprises the following steps:
- a) fractionating dry milling of the grains, wherein the grains are separated into a starch-comprising endosperm fraction (flour) and a bran fraction;
- b) converting the endosperm fraction into an aqueous suspension;
- and
- c) liquefying and enzymatically saccharifying the starch components of the aqueous suspension, obtaining an aqueous glucose, wherein the aqueous suspension has a starch content of at least 30% by weight;
- and
- wherein the gluten proportion present in the endosperm fraction is depleted from the aqueous glucose obtained in step c) and/or from the aqueous suspension of the endosperm fraction before carrying out step c).
